Marc Bloch held that there were no random coincidences in history, but also no unilateral or simplifying causation, as is indicated in the context of this review. Perhaps the constant anxiety of the authors about fair conditions for knowledge is what unites searchers for the truth in all civilizations and at all times and places. However, the search for truth is contingent on the search for freedom, and hence the consistency or harmony between two historical choices for Marc Bloch: the choice to fight for freedom, and the choice to search for historical truth. Perhaps the two choices are two aspects of a single view.
